Any number of things could be wrong.

First, does he have a hardware firewall between him and the modem? If so, it probably does NAT and port-forwarding, but you need to specifically allow port 22 or another port open to connections from your IP, and have it forward to his PC on port 22.

Next, software firewall, add a rule to allow connections from your IP to his port 22.

Greetings,

I am looking for help on how to get ssh working for a client. I recently converted a client over to Linux for one of his computers. I have ssh running on his machine, but things are not the way they should be.

Here's the thing, the computer is using a private ip address. So in order to find out what his ip address was, I connected from his machine to one of mine, thus capturing the ip address in my logs (sure I know there are other ways).

So, when I try to connect from my machine, to his I get connection refused. While I can ping his box, and it appears to be up, neither ssh nor telnet work. I didn't really expect telnet to work. Is there something that SWB does to prevent this? Or could his modem be rejecting ssh? Another possibility I can think of is, when I installed Ubuntu on his machine it installed a firewall.

Anyone?

Thanks, Brian JD
